Time series data are collected at what intervals?

Time series data are collected at what intervals?

• A. Data collected at irregular intervals
• B. Data collected at regular intervals
• C. Cross-sectional data
• D. Panel data

Answer: (D)

Time series data are observations of a variable collected over time at equally spaced time points, such as daily stock prices or monthly sales. This regular spacing is essential for most time series methods because it allows the model to capture how values evolve from one time point to the next and to apply techniques that assume a fixed time gap between observations. Data collected at irregular intervals are not typical time series; cross-sectional data come from a single point in time across many units, and panel data combine observations over multiple time periods for the same units. So, time series data are characterized by data collected at regular intervals.
